GUSTAV HAUT, OF PERHAM, MINNESOTA.

BRICK-MACHINE.

SPECIFCATION forming part of Letters Patent No. 339,881, dated April 13, 1886.

Application filed November 30, 1885. Serial No. 184,225.

To @ZZ whom it may concern:

Be it known that I, Gusrav HAUT, a citizen of the United States, residing at Perham, in the county of Otter Tail and State of Minnesota, have invented certain new and useful Improvements in Brick-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in brick-making machines, and is designed to produce a device for forming or molding moist or wet clay into blocks of suitable size and shape; and it consists in ,the arrangements, combinations, and constructions of parts, as hereinafter set forth, and pointed out in the claims.

In the drawings, Figure l represent-s a vertical longitudinal section of the machine, and Fig. 2 a detail perspective of the mold-box. Fig. 3 is a transverse section taken through the machine in the vertical plane indicated by dotted line a a.' on Fig. l.

The main frame A has on each side an eX- tended longitudinal timber, B. These timbers form tracks for the wheels or rollers C of the carriage D. From each side of this carriage extend pitmen E,which connect to the crankarms'l?, on each end of a transverse shaft, G. J onrnaled in the main portion of the machine are the timbers H,which latter are interior to and parallel with the extended timbers B. On the shaft G is a bevel-pinion, Lwhich meshes with a bevel gear-wheel, K, supported loosely on the lower end of a vertical shaft, L, provided at its upper end, above the top of the frame, with a drive-pulley, M, by means of which the power may be applied.

The wheel K has a collar, N, with its upper edge toothed, and the shaft L carries an annularly-g'rooved spring-retained toothed collar, O, which normally engages with the said collar N and causes the wheel K to revolve with the shaft L, but may be moved longi tudinally on the saidshaft when it is desirable to stop the said wheel. As is evident, the revolving of the shaft G will cause the car- (No model.)

riage tov have a reciprocatory travel on the timbers B.

On the carriage rests a sliding frame having one part (designated by P) higher than the other portion,(which is designated by R,) the latter forming a seat for the mold-box S, so that the top of the said box shall be on a level with the top of the higher portion I). The box S consists of a series of ycompartments of the proper size and shape to form the bricks.

The main frame is covered by a platform, T, for the reception of the clay, and has at one end a downward extension or decline, U, which leads to a series of passages, Y, in a frame, 1V, resting or supported directly over the frame supported by the carriage. At each end of this portion of the machine are erected the posts X. with slots at the upper end, as shown at Y, the said slots forming supporting guides for the transverse timber Z, from which depends the plunger' A', guided, in a measure, by the box B', supported on top of the frame XV. The timber Z has passing through it, near each end, aspring, C2, surrounded by threaded rod C', at the upper end of which is a sprocket-Wheel, D'. The said sprocket-wheels are connected by a suitable chain, and eachis internally threaded so as to move on the threaded portions of the rods. One of the sprocket-wheels is provided with an operatinghandle, E', so that by turning it the tension of the springs on each rod may be equally regulated. Each rod is connected by means oi' a pitman,F', to a wheel,G', with a series of teeth ou the periphery, and pivoted to the posts X. The teeth on the Wheel or pinion G are adapted to engage with a raclebar, H', on the carriage, the number of teeth in each being sufficient to carry the plunger A down and up.

The top of the portion P may be metal-lined to prevent wear, and the bearing portions of the frame NV may also be metal-lined. The slot V has dividing-strips I', which divide it into as many compartments as there are in the mold-box S.

At the inner end of the frame on the carriage are pawls K', which are spring-retained and cause the said sliding frame to move as the carriage is carried under the main portion ofthe machine. When the mold-box S has reached a point directly under the frame XV, the pawls IOC ` mold-box from under the fratne WV, the bottom of which smooths off the top of the newlymade bricks. While the above operation is being performed, the pawls K drop to their places and the plunger is raised.

On a crosstimber between the timbers B is pivoted an upright lever, N', which is connected by means of a chain, O, passing around a pulley, P, to a lever, R, having one end bifurcated, as shown at S, and embracing the collar O, pins in the said end S resting in the said annular groove in said collar.

Under the carriage extends a rod, T', having one end bent so as to normally engage the upper end of the lever N when the carriage,

has nearly approached the outward limit of its travel. The said rod moving the lever causes the clutch on the main shaft to disengage from the large gear-wheel, and thus stop the carriage. The box S may then be removed and a new one substituted.

By turning the rod by means of the handle U thereon the lever is released, the clutch falls into place, and the operation of pressing the clay into the mold-box is repeated. A spring, V', causes the rod T tofassume its normal position after being operated to release the lever N.

The spring-rods on the plunger prevent any damage from stones in the clay, allowing the said plunger to give on encounteringobstruc tions.

I claim- 1. Combined with a movable carriage, in a brick-machine, a plunger having a cross-tim1 ber carrying spring-surrounded rods, toothed wheels on the plunger-supporti ng frames and connected to the said rods, and rack-teeth on .the said carriage operating said wheels, substantially as specified. l

2.v In a brick-machine, a drive-shaft with a clutch-connection to the transmitting mechan` ism, a lever for operating said clutch, a reciprocating carriage, a catch on said carriage,

and a lever pivoted to the frame connected to lthe clutch-lever and adapted to engage the catch on the carriage, substantially as specified. -3. The combination, with the reciprocating -carriage D, mounted and actuated substantiall y as described, of a sliding frame thereon having an elevated oor and a depression in front of it to receive the mold-boxes, the sta-A tionary pressing-box` located over said slide and provided with a plunger connected to a vertically-,movable guided cross-head, the rods o, vertically movable through this cross-head and bearing sprocket-wheels tapped on them and connected by an endless chain, and seated on springs, the toothed wheels G', connected by pitmen to said rodsc, and the racks H on the carriage, all constructed and adapted to operate substantially as described.

4. In a brick-making machine, the combination, with'the press-box, its plunger, anda carriage bearing rack-teeth, of the springseated rodsV passed freely through the crosshead of the plunger, the toothed wheels actuated by said rack-teeth and connected to the said rods by pitmen, and the sprocket-wheels tapped on said rods and connected by an endless chain, substantially as described.

5. In a brick-making machine of the character described,the combination, with a pressbox, a rolling carriage, and a sliding frame riageat the proper times for removing the inold-boxes, substantially as described.

. In testimony whereofI aix my signature in loo presence of two witnesses. i
